Technically I was named after a family name from a play(the play was based on a book), BUT, the same author(Earl Hamner Jr.) wrote another book with the same family, and it was made into a movie. Spencer's Mountain. Before they were called The Waltons, his fictional family was called The Spencers!
Mommy gave me this name because on her way home from auditioning for the play The Homecoming(also made into a movie, but in it they were called The Waltons), I ran out in front of her car. She got out, scooped me up, and brought me home, and here I am! She says I was good luck, too, since she got the part she wanted!
